Subtract 2x from both sides
6x-4=-3
add 4 to both sides
6x=1
divide 6
x=1/6
Answer: x=5,-5
Explanation:
Take the root of both sides and solve.
Answer:
A) 440.44 units³
B) similar figures
C) 1486.485 units³
Step-by-step explanation:
Volume = ⅓× base area × height
= ⅓ × 110.11 × 12 = 440.44 units³
B) he doesn't have to make calculations again because the two pyramids are similar.
If the ratio of sides is given, he can find the other volume using:
(side1/side2)³ = volume1/volume2
(2/3)³ = 440.44/volume2
Volume2 = 440.44 × 27/8
Volume2 = 1486.485 units³
Points C and D are equidistant from points A and B, so Dominic's square could be ACBD. To draw that square, his next move should be ...
... Use a straightedge to join points C and A, C and B, D and A, and D and B
